The 301EM was specifically designed to meet ASHRAE 15, B-52, and international mechanical code requirements. It can be configured to offer automatic fan, horn, and strobe activation.
The 301EM can be placed in a location that is separate from the detection area, making it safer to monitor the gas. It can have up to 20 sensors connected to it to get accurate readings of lower gas concentrations.
- Three alarm levels
